Answer:Several theories have been proposed for the formation of desert pavements. A common theory suggests they form through the gradual removal of sand, dust and other fine-grained material by the wind and intermittent rain, leaving the larger fragments behind.
Explanation: scientists have had sever theories as stated in my answer above
The characteristics that apply to viruses are;
- Viruses are made of RNA or DNA.
- Viruses have a protein coat
<h3>What are viruses?</h3>
Viruses are microscopic non-cellular structure consisting of a core of DNA or RNA (nucleic acid) surrounded by a protein coat (capsid).
A virus is considered as by non-living because it requires a living host cell to replicate, and often causes disease in the host organism.
Therefore, the characteristics that apply to viruses are;
- Viruses are made of RNA or DNA.
- Viruses have a protein coat

The main dietary factor associated with elevated blood cholesterol is saturated fat.
<h3>
What about saturated fat?</h3>
- Because they increase the amount of LDL cholesterol in our blood, saturated fats, sometimes known as "bad fats," increase the risk of cardiovascular disorders (including heart disease and stroke).
- Cholesterol that is circulated in the blood.
- The majority of this cholesterol is produced by the body, however some is also absorbed from the meals you eat.
- Even if they include fat, foods derived from plants never contain cholesterol.
- Only foods from animals do. Low density lipoproteins are able to transport cholesterol.
- Dietary fat, particularly saturated and trans fats, may increase LDL and total cholesterol levels in the blood.
- Blood cholesterol levels may be lowered by substituting polyunsaturated and monounsaturated fats, particularly olive and canola oil, for some saturated fats.
- When we consume too much saturated fat, the receptors stop functioning as effectively, and blood cholesterol levels rise.

Answer:
<u>A. red blood cells containing malaria</u>
Explanation:
Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite <em>Plasmodium sp.</em><em>,</em> which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.
When they multiply within the red blood cell, they <u>burst the red blood cell open</u>, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.
Malaria is a deadly illness, causing harm to its hosts, and in many cases death. <u>Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.</u>
